What are TThe effects of sodium and calcium intake on blood lead levels in pregnant and lactating women?
Although our skeleton was “predominantly” considered a location for sequestration of absorbed lead, bone is not simply an inert location. Once deposited in the bone, lead from the bone can be remobilized back into the bloodstream, however, for example, we’re losing bones osteoporosis. Even normal menopause can do this and raise lead levels as our bones start to lose their integrity, Bthe end the biggest concern is the “mObilization of long-term lead storage from the maternal skeleton…during pregnancy and breastfeeding.” In order In order to keep maternal lead levels as low as possible during this critical phase, we need to minimize bone loss.
How shall we do it? As I discuss in my video Should pregnant women take calcium supplements to lower lead levels?, “Habitually exaggerated” NaCl [salt] Ingestion could be a factor advancement Bone loss. “So is there a connection between the mother’s sodium intake and blood lead levels during pregnancy? Researcher found that there was a higher salt intake connected with with higher lead levels, but only for women who consumed less than 840 mg of calcium per day. “NSe findings …suggest that appropriate That [calcium] with a low on [sodium] Ingestion can play a positive role in lowering blood levels Pb [lead] Concentration in pregnant women. ”
A higher calcium intake was made connected with with lower blood lead concentrations during pregnancy, but you won’t know if it’s cause and effect unless you test it.
What if u given Calcium Supplements For Women? I have before explored how milk can actually make things worse, but what about pure calcium, especially for women with low calcium intake?? Study participants, African women who had been receive only 350 mg calcium per day, what’s just 35 percent of 1000mg RDA, became given a whopping 1,500mg from Daily Calcium. That protects their bones, to the right? As you can see in mine at 2:00 Video, weatherwithout the calcium when the women were receive only With 350 mg of calcium a day in their diet, they lost some bone in their spine and hips. How did they feel when the researchers gave them? 1,500 mg calcium per day? she even lost more bone. The women who received the calcium supplements had a significant one lower Bone mineral density in the hip and greater bone loss in the spine and wrists.
What happened? It looks like the explorers screwed them up Ladies natural adaptation of the body. At the beginning of the course tHey would have only been meal 350 mg calcium per day. Because our body is not stupid, They are maximum absorption and Loss minimization. Then, the explorers stepped in with calcium pills and undermineD. the whole process, turning away from these adjustments and leavinging Your body thought they would always get thisÖse massive calcium Cans. W.When the study stopped women went into a large calcium deficit and had to steal more of her bones. The researchers later went back and thought that though the women who had been in the placebo group, those given the extra calcium recovered but continued to suffer from the effectsas you can see at 3-04th in my Video.
What about western women? who are already record more than 1,000 mg calcium a day? Want give give them an additional 1,200 mg per day reduce some of this bone flow? Yes, the bone resorption appeared to be around 16. to reduce percent, “and, can therefore be a practical intervention to prevent the temporary skeletal loss associated with childbirth” that could release trapped lead, but you won’t know until you put it to the test.
In another paper from the same study, the Researcher measured what about the women Lead steps. Tcap come round Bone borrowing led to a decrease in lead release. As such it is can help lower lead Exposure to both the fetus and of the infant, as breastfeeding benefits remain. Ok bthe end the women in this study became Life in Mexico City, where they possibly lead-glazed ceramic with lead concentrations of up to 10. have been exposed and / dL. What about women with lead levels below 5, closer to the current US average? and / dL?
Researchers randomized half the breastfeeding women in your studies to to take 500 mg extra calcium per day. As you can see in mine at 4:25 Video, The leads levels both groups started equal during pregnancy. In the non-supplemented group are these levels shot up during breastfeeding as some of the lead was believed to have been loosened from her bones. In group getting the Daily 500mg Calcium supplement, However, there was no Lead in your bloodstream will increase, causing “Evidence that taking calcium supplement during Breastfeeding [breastfeeding] can effectively limit the mobilization of lead from the bone stores and thus the risk of lead transmission to the breast-fed child mothers [breast] Milk.”
Regardless, Breast is still best. Complement or not, “the risks are predominated until Services the chest Milk consumption,” but calcium supplementation can help to reduce any risk even further. Naturally, it is better not to build up lead in the bones in the first place. As a famous occupational medicine paper place it a half–A century ago there are all methods of dietary intervention, but there is only one way impede Lead poisoning: D.Don’t even get poisoned. AAnything else just distracts attention from treating the underlying cause.
For other toxic heavy metals such as Mercury, for example women are “devices to avoid consuming predatory fish”– that is, fish-the-other-eat-fish–“while pregnancy and decrease when breastfeeding MeHg [mercury] Exposure.” Actually, they should start even before pregnancy. As a matter of fact, “Wives of the child–Wearing age and nursing mothers should avoid eating fish-eaters [fish-eating] Fish” avoid building the mercury in the Body first. And, for lead, which means not living near a hut and avoiding smoking.
There IThis is another way to detoxify your body of lead to protect some of your future children, but it’s not ideal. Do you remember the menopausal study in which postmenopausal women had higher levels of lead in their blood than premenopausal women? Well, even higher were postmenopausal women who would have never had children. As you can see in mine at 6:00 Video, “The post menopause increase the lead content was lower in women with previous pregnancies ”, presumably because they had already detoxified some of their lead from their children.
THE CENTRAL THESES
- Once deposited in the bone, lead can flow back into our bloodstream in the event of bone loss, for example due to osteoporosis, menopause, pregnancy and breastfeeding.
- Researchers found that higher salt intake in women who received less than 840 mg of calcium per day was associated with higher lead levels, and suggest that adequate calcium intake with low sodium intake may help lower blood lead levels in women during pregnancy Can be an advantage.
- When African women who consumed 350 mg of calcium daily from their diet (only 35 percent of the recommended daily allowance) received 1,500 mg of calcium per day as a dietary supplement, they lost even more bones. It appears that their natural adaptation was disturbed and their body awaited the massive influx of calcium so that after the study was completed they ran into a large deficit and stopped taking the supplement so that more calcium was withdrawn from stores in their bones.
- The researchers randomly assigned an additional 500 mg daily calcium intake to breastfeeding women and found that lead levels increased in the no-supplement group during breastfeeding, likely due to the release of lead from their bones, while blood lead levels did not increase in the Group took 500 mg of calcium daily, suggesting that calcium supplementation during breastfeeding may limit lead mobilization from bone stores and reduce the risk of transmission to breastfed infants.
- Breast milk is still preferred, but calcium supplementation can reduce further risk.
- Avoiding lead poisoning is just as important as avoiding other toxic heavy metals like mercury, which are found in many fish.
In case you missed the last video, The rise in blood lead levels during pregnancy and menopause provides some background information to this topic.
